It could be your SRAM module, It could be the battery but you should see a BAT on the display. Or yes it could be your power supply.

It could also be as Petro has already stated the data that you are entering. You can get the alarm to clear by clearing the memory in the machine but it comes back after you reload the data. Are you reloading the programs?? Try reloading only what you need to run the control (no programs). See if the alarm is there. If not then load your programs. If the alarm appears then you have an issue with your program memory.
